The Centers for Disease Control and Prevention says it is tracking a rise in stomach illnesses caused by infections with "extensively drug-resistant" bacteria that leave doctors with few antibiotic options to treat patients. The CDC warns it now poses a "serious public health threat."
Over the past few years, the CDC says there are signs the percentage of Shigella bacteria cases that are resistant to a broad swath of antibiotics has begun to climb steeply around the country. These strains can also spread their resistance genes to other stomach bugs.
Analyses of these bacteria, dubbed XDR Shigella, have shown resistance to all of the typically recommended frontline antibiotic treatments for bacteria: azithromycin, ciprofloxacin, ceftriaxone, trimethoprim-sulfamethoxazole, and ampicillin.

WASHINGTON — An American intelligence assessment of the Ecuadorian presidential election, set for Sunday, concluded that a reelection of the incumbent president would better serve U.S. national security interests over the challenger. The assessment comes as the Trump administration mulls establishing a permanent U.S. military presence in the South American country, once known as the "island of peace," to help battle violent gangs, CBS News has learned.
